DOUBLETREE-CLIR' SPECIFICATION formingpart of Letters Patent N0. 734,736. dated July 28, 1903. Application filed May 18, 1903. Serial No. 157,612. iNo model.)

To all whom it may concern.-

Be it known thatI, CHARLES W. MoGLAsH- AN, asubject of the King of England, residing at East Otto, in the county of Uattaraugus and of the clip. Fig. 7 is a side elevation of the.

State of New York, have invented new and useful'Improvementsin Doubletrees,of which the following is a specification.

This invention relates more particularly to the-draft attachments employed for connect ing an evener or doubletreeto a wagon-pole or a plow, harrow, or other implement.

forming a draw-bolt hole in the evener, thereby avoiding weakening of its central portion which receives the greatest strain.

In the accompanying drawings, Figure l is a top plan view of an evener provided with my improvement, showing the same applied to a wagon-pole. Fig. 2 is a fragmentary rear View of the evener. Fig. 3 is a fragmentary front view thereof. gitudinal section in line-1 4, Fig. 1, on an enlarged scale. spective views of the upper and lower plates evener, showing the same attached to a plowbeam. Fig. Sis a vertical section of the clip, showing the same modified in construction for use at the ends of the evener.

' f Similar letters of reference indicate corresponding parts throughoutthe several views.

A indicates a wagon-pole; B, an evener or doubletree; G, the swingletrees, and D the customary hammer-strap.

In the construction shown in Figs. 1 to 7 my improved clip is applied centrally to the evener B and consists of a pair of similar parallel plates E E, preferably of sheet metal, ap-

plied to the upper and lower sides of the evener. Each of these plates is provided at its front and rear edges with integral lips or flanges e, which are bent or clenched over the front and rear sides of the evener, the lips ofthe upper plate being bent downwardly and The lips the clip-plates firmly thereto. A comparatively light rivet or bolt f preferably passes through the top and bottom plates of the clip and the evenernear the front edge of the lat- Fig. 4 is a vertical lon-' Figs. 5 and 6 are detached per most favorable direction.

ter, as shown in Fig. l, for more reliably holding the plates in place. Each of the clipplates is also provided at its front and rear edges between the lips c with integral lugs or ears 9 g, which project horizontally beyond the adjacent sides of the evener and are arranged substantially in the plane of the plates. The lugs of the two plates are arranged directly opposite each bther and provided with coinciding openings h h. The openings 71 of f the 'front clip-lugs are adapted to receive a The object of myinvenlion is to provide the evener with a light, strong, and durable attac-hing-clip which obviates the necessity of draw-bolt I when the evener is applied to a wagon-tongue, as shown-in Figs. 1 and 2, While theopenings h of the rear clip-lugs are adapted to receive a connecting-bolt J, to which is applied a ring or suitable attachment K for connecting the evener to a log or to a plow, harrow, or other implement, as illustrated in Fig. 7. When the evener is used on a wagon-tongue, the hammer-strap D is preferably passed through the ring K, as shown in Figs. 1 and 4. This prevents the strap from flying up and withdrawing the bolt 1, which would be liable to cause an accident.

As shown in Figs. 4, 5, and 6, the perforated portions of the clip-lugs are depressed below the outer surfaceof the lugs, so as to countersink the head and nut of the connecting-bolt J. By this construction the upper and lower sides of the clip are left smooth over their entire surface and the bolt is prevented from catching on obstructions when the evener is dragged over the ground.

A space-block or sleeve L is preferably interposed between the rear lugs g for preventing the same from being bent or drawn toward each other. The connecting-bolt J passes through this sleeve and holds it in place.

As my improved construction avoids the use of the bolt-hole ordinarily formed in the evener, the consequent weakening of the evener is obviated, and as the two-part clip embraces the evener on all sides it greatly strengthens the same.

By arranging the lugs g g in line with the upper and lower plates of the clip the draft strain is exerted directly in the planeof the plates, thus utilizing their strength in the This permitsthe clip to be made of comparatively light stock. In the modified form of the clip (shown in Fig. 8) the same is adapted forconnecting the swingletrees O to the ends of the evener. In this case the clip is composed ofupper and lower plates-E E, applied to the upper and lower sides of the evener and each provided at its rear edge with a lip e, which embraces the adjacent side of the evener, and

at its front end with a projecting perforated lug or ear g The lugs of the two plates coincide with each other like the corresponding lugs of the first-described construction and are connected by a bolt J, the lugs being held apart by a space-block or sleeve L. The rings M of the swingletree receive the bolts J.

I claim as my invention- 1. The combination with a whiffletree, of a clip comprising a pair of plates applied to the upper and lower sides of the tree and provided at one edge with integral lips which are bent over the side of the tree and at the opposite edge with opposing perforated lugs arranged in the plane of the plates and adapted to receive a bolt, substantially as set forth.

2. The combination with a whiffletree, of a clip comprising a pair of plates applied to the upper and lower sides of the tree and provided at one edge with integral lips which are bent over the side of the tree and at the opposite edge with opposing perforated lugs adapted to receive a bolt, the portions of the lugs containing the perforations being depressed for countersinking the head and not of said bolt, substantially as set forth.

3. The combination with an evener or doubletree, of a clip comprising a pair of plates applied to the upper and lower sides of the tree and provided at their front edges with perforated lugs adapted to receive a drawbolt and at their rear edges with opposing separated lugs, and a bolt connecting said rear lugs, substantially as set forth.

4. The combination with an evener or doubletree, of a clip comprising a pair of plates applied to the upper and lower sides of the tree and provided at their front and rear edges with lips which embrace the sides'of' applied to the upper and lower sides of the tree and provided at their front and rear edges with lips which embrace the sides of the tree, said plates being provided at their front edges with opposing perforated lugs adapted to receive a draw-bolt and at their rear edges with opposing separated lugs, and aboltconnecting said rearlugs, substantially as set forth.

6. The combination with an evener or doubletree, of a clip comprising a pair of plates applied to the upper and lower sides of the tree and each provided at its front and rear edges with lips which embrace the sides of the tree and between said lips with perforated lugs arranged substantially in the plane of the plate, the lugs of the two plates coinciding with each other and each pair of lugs being adapted to receive a bolt, substantially as set forth.

7. The combination with an evener or doubletree, of a clip comprising a pair of plates applied to opposite sides of the tree and provided at their front and rear edges with'perforated lugs and with lips which embrace the sides of the tree, a bolt passing through a pair of said lugs, and a space-block or sleeve applied to said bolt between the last-named lugs, substantially as set forth.
